Sia is being disowned by fans over her MAC collab

For the past 23 years, MAC's Viva Glam campaign has been one of the brand's most beloved creations. It's raised hundreds of millions of dollars for HIV/AIDS-awareness charities and has been fronted by some of the world's most notable faces including Rihanna, Ariana Grande, Nicki Minaj, Elton John, and many more.

The brand just announced the next face of its historic campaign — and it's already getting that person is a lot of trouble.

Sia is the latest face of MAC Cosmetics' Viva Glam campaign, and her fans wish she wasn't.

A little bit of context for you: MAC itself does not perform cosmetic tests on animals. However, people in the vegan and cruelty-free communities prefer to avoid brands who actively choose to expand to China, where government animal testing is 100% guaranteed to happen.

That's why NARS Cosmetics got flamed by animal rights activists earlier this year when it announced it would start selling its products in Chinese retailers.

And it's making things rather difficult for Sia's fans, many of whom only support vegan and cruelty-free brands.

Honestly lost so much respect for Sia. Mac Cosmetics is NOT cruelty free (once upon a time they were) & are trying to pass the blame on China for the animal testing of their products. They are NOT exempt from blame for the animals suffering. Selling in China is a choice THEY made

Like M·A·C, I believe makeup shouldn’t be tested on animals. M·A·C does not test on animals and is advocating change in countries like China where animal testing exists. For more info, read here: https://t.co/KplrHIvkpG

Because Sia can't singlehandedly prevent her lipstick being sold — and animal tested — in China.

Unbelievably irresponsible of you to share this misinformation @Sia. @MACcosmetics sell to China where animal testing is required by law! MAC are absolutely NOT cruelty free and do not deserve that status. pic.twitter.com/eswLDOVsdr
